Review of “The History of Large Federal Dams: Planning, Design, and Construction,” Published by the U.S. Department of the Interior.

This isn’t my usual reading fare, but I couldn’t pass it up because dams are fascinating to me personally. This book is a collection of essays written by engineering historians. They are all well written and easy to comprehend, even the chapter on dam design criteria.

Let the reader be warned, however; this is definitely a historical book, not a book about dams. The authors carefully describe the complex political, economic, and technological problems associated with the construction of hundreds of dams — that’s right, hundreds of dams were constructed by the Reclamation Bureau and the Army Corps of Engineers between 1930 and 1970. This is often referred to as the big dam era, really getting started with the commissioning of Hoover Dam in 1935. But it was far from an easy time for mega projects, and environmental and other considerations finally created enough pressure to end the epoch.

The big dam era was characterized by multipurpose dams, i.e., dams that provided hydroelectric power, flood control, irrigation, and/or river navigation. This collection of essays does a great job covering the entire period.

I never intended to read this book but I was fascinated; however, I skipped a lot of detailed historical facts. If you’re interested in American technological history, this book’s for you — if you can find it …

Review of “The Biggest Ideas in the Universe: Quanta and Fields” by Sean Carroll

I listen to Sean Carroll’s podcast, Mindscape, every week and he’s always referring to his series of popular science books. This is the second, which does a pretty good job of explaining all things quantum and how they’re applied to the physical world.

There is some math, but it helped me better understand the underlayment of our reality, what I call “subspace” (my phrase not his). The concept of EFFECTIVE FIELD THEORY (AKA quantum field theory) is a good example of the old adage, “what goes around comes around”: physicists are back to the ether concept, which was put to rest at the beginning of the twentieth century. Now, instead of one metaphysical field permeating space, we have an infinite number, which through their interactions create particles, atoms, molecules, and life.

There are a few tricky steps, but this book does a pretty good job getting the gist of our best theory of reality across to a reader who isn’t afraid of mathematics.

A few ideas weren’t explained sufficiently, probably because physicists take them for granted, so I had to resort to Wikipedia a few times. Of course, the probability of my remembering any of this is negligible, so I’ll keep this one on the bookshelf rather than donating it.

I recommend it but, if you aren’t familiar with classical (Newtonian) mechanics, I’d suggest watching these videos first.
